It is possible to change variables to make the kinetic term canonical, non-singular and to express the rest of the action in these variables. The potential and the fermion action at small \(t\)  are complicated and might still involve terms singular in the \(t\rightarrow 0\)  limit.
But since there is no extremum of the potential at \(X\ne 0\)  and \(T\ne 0 \)  for \(t\rightarrow 0\)  the procedure of switching to canonical variables does not help to define the physical states and the masses of these canonical fields. It only shows that the limit to theories with non-linear supersymmetry from the model in [1]} is discontinuous: the scalars go to 0 first and \(t\rightarrow 0\)  afterwards, or vice versa, the results are different.
